Could you also provide change to configure.ac, so that ./configure
would detect if we have gettext installed or not?  Thanks in advance.
Here's a check that just checks if we have libintl.h similar to the
existing checks for libgen.h and other headers.

Do you think this be adequate?
I'm not sure.  If NO_GETTEXT is used only to protect '#include <libintl.h>'
it might be enough.

The getext documentation says that `gettext.m4' defines AM_GNU_GETTEXT
macro that tests for the presence of GNU gettext function family.

The complication is that `gettext.m4' might not exist, and then
AM_GNU_GETTEXT would be not defined.  So if we are to use
AM_GNU_GETTEXT, we should I guess protect it with m4_ifdef():

  m4_ifdef([AM_GNU_GETTEXT], [AM_GNU_GETTEXT([external])])

or something like that.  And of course we need to work around the fact
that AM_GNU_GETTEXT sets USE_NLS to either 'yes' or 'no' instead of
setting setting NO_GETTEXT to either non-empty or empty value.

Or we can do something similar to what we do for NEEDS_LIBICINV /
NO_ICONV, namely make ./configure compile simple test program using
gettext.

Cc-ed Ben Walton and David M. Syzdek: perhaps they can help with this
issue.
